Instant search engine optimized for developer happiness. Its GPL-3.0 license keeps the project and its forks open-source forever, and commercial use is allowed. Because it is self-hostable, your data can stay entirely on your own infrastructure.
Switching from Elasticsearch without the drama
- Export your data from Elasticsearch first — most tools above can import standard formats.
- Run your top pick in parallel for a week or two before committing; self-hosted options can be tried locally in minutes.
- Migrate one team or one project at a time, keeping the old account read-only until everything checks out.
